Preimplantation genetic testing for aneuploidies (PGT-A) is commonly used in IVF but requires embryo biopsy and shows limited benefit in egg donation cycles. Non-invasive PGT-A (niPGTA), based on the analysis of cell-free embryonic DNA in spent culture media, offers a promising biopsy-free alternative. This prospective, blinded study in egg donation cycles will evaluate whether niPGTA-detected aneuploidy is associated with implantation failure and pregnancy loss, assessing its potential clinical value as a non-invasive embryo selection tool.
